I have no idea what "if not flat" means.  If the height is given as "0" of course its flat!  You're creating a spiral not a helix.

Hello N 3
If you are using HELIX in a 2D drawing, beware of not creating a 3D HELIX.
In the properties panel you've got access to 10 modifiable values.
Position X ........
Position Y .......
Position Z 0  ---> must be zero
Constrain your choise between 3
Height 0 ---> must be zero
Turns ---> your choise
Height of turns 0 ---> must be zero
Base radius ---> your choise
Top radius ---> your choise
XXXXX ( I don't know in english ) trigo or time direction
( excuse me for the terms in french to english )
 
Please let us know if it helped and if possible let us see your DWG, I'm interested.

You're drawing a 2D spiral which means there is NO height!  Which is why I told you to use a value of "0".

A helix with a different radius for the base and the top will produce a spiral.  If the radii for both is the same then you won't get the desired result.

This is what you are looking to achieve right?

Guess what?  That is not going to give you what you want.

What is your base radius?
What is your top radius?
How many turns do you want?

I Enter this

center point
number of rotations:5 
Growth per rotations: 10 
Points per rotation <30>: 90

its flat spiral.

hmp, how do i fix to not flat.
Thanks,

You have a habit of not answering questions put directly to you.  I did NOT ask what spiral.lsp was requesting for input.

Please answer MY questions.
